first off guess your tools don't get dirty... try tearing down a printing unit covered in ink ,
BTW bleach and sulfuric acid would not cut the ink / grease
what do you use to clean your tools with ??
Sorry if I was harsh. I did not really consider those who do this full-time and work on others' cars. Also, to those in the salt belt- I feel for ya!
I try to keep every single part of my vehicles CLP (clean, lubricated, protected/preserved). So when I do use tool, they really dont get dirty. And when Im done with a job, I try to wipe them with something or just about anything. It doesnt really take an exact chemical or product to clean.
I have what I consider mid-level tools. So those of you with the highest strength and quality chrome may do different or may not need much attention at all. Then those of you with bottom basement socket sets may require alot of attention from you.
I will try to be brief, but without sacrificing being thorough. So here goes.
I usually pre 'treat' a tool when new and before ever using it. First of all, I probably wont take it out of the carton/wrapper until I do need it. But when I do first get ahold of it I will generally oil the metal parts. I have been known to oil the tips of screwdrivers, but I think that was a mistake as it may make them cam out more easily.
Lets take a socket set I got several years ago. It is entry level and all six point and comes in a plastic briefcase. I took, IIRC, every socket in it and wipes them down the best I could with WD-40 and a towel of some sort (blue shop towel, paper towel, microfiber, oil rag- it doesnt really matter because we are all different and while some may work better for some on some things, basically any care you take is good). So I would spray the sockets or towel with WD and wipe them. Same with the ratchets and allen keys included in the set. After doing this initially, then whenever it 'needs' it or whenever you feel like it, or even just wiping some kind of oil on a single socket at a time as you use them will, in my opinion, greatly increase their worth.
Increasing their worth is a kind of universal language. First off, we want the tool to grip the fastener and remove it without breaking or damaging it/rounding the corners/points, we dont want to bust our knuckles or get a cramp or tweak a wrist, having it do this everytime we need it to and not deteriorate in the process, keep rust at bay, and not burn your hands when you pick it up(no toxicity).
So, is paragraph will try to answer all the scenarios in the above/previous paragraph. Metallurgy! Maybe snap-ons and Cornwells will have advanced casting techniques, premium ore, and top notch oil quenching- so that may leave the mechanic with less need to tend to the tool(we're talking sockets). So, it seems the socket should crack before it rounds, grinds, or even deforms/bend. Because, either way the tool is now scrap, but by cracking/fracturing, I think it would not harm the bolt/fastener. So, maybe by keeping the tools clean and oiled- we can make them stronger (in many ways), feel better in the hand, stay clean and rust free. I read somewhere that a guy bought a socket set, and the point was, that he never used his odd size 9mm until like twenty years down the road- and it broke easily. Maybe he never tended to it and just hammered down on it the first time he used it in twenty years of ownership. Like a car sitting, if you just leave it parked under a tree in the front yard for twenty years- it will probably be junk. Even if you wash it every month, it will then just be a less dirty piece of junk. We need to keep it in good order so the restoration guys dont have to have a go at it.
As for tools, keep some kind of oil on the metal (bicycle lube, gun oil, motor oil, silicone spray, cooking oil- SOMETHING...... Then the grips of pliers, hammers, etc....maybe armor all or some hand cleaner. Ratchets, if they come dry and you want to- then grease them, but if they wont open or parts want to fly or you dont know how to reassemble it- just soak it in hot oil or something like that. Key is to prevent degradation. For screwdriver, you can use a brush for the tip (nylon if slightly gritty, or a steel brush for terrible conditions), then some oil from the oil can (above fluids, or transmission fluid, gear oil, psf, whatever smells good to you. Then for the grip, use a car wash soap mixed with distilled water in a spray bottle. Spray that on there and see.....
